Specifically, for example, the location information record may be in CSV (Comma-Separated Values) format, JSON (JavaScript (registered trademark) Object Notation) format, text format, XML (Extensible Markup Language) format, or other conventionally well-known data. format It may be composed of

Here, conventionally, there has been known a method of managing the operation of a moving object using position information of the moving object. For example, a method of managing vehicle operation using single-distance wireless communication such as "ETC 2.0" provided by the Ministry of Land, Infrastructure, Transport and Tourism is known (Japanese Patent Application Laid-Open No. 2017-134757). However, just as ETC roadside devices can only be installed at expressway toll booths, fixedly installed roadside devices cannot obtain location information of moving objects at locations other than the installation location. Therefore, it was difficult to understand and manage the entire operation of the mobile vehicle.

In contrast, the information processing device 100 according to one embodiment acquires the location information record of the communication device 200 mounted on the mobile object, and determines the movement pattern of the mobile object based on the acquired multiple location information records. However, the identification information of the communication device 200 and the movement pattern of the mobile body can be recorded in association with each other. According to this, the movement pattern of the mobile body can be determined based on the plurality of location information records acquired from the communication device 200 mounted on the mobile body to be managed, and the movement status of the mobile body can be recorded. As a result, the administrator can know the location of the mobile object from the past to the present and its transition from the location information record of the mobile object obtained at any location, so the administrator can understand and manage the entire operation of the mobile object. can do.

The information processing device 100 will be explained with reference to FIG. 2 again. The control unit 110 of the information processing device 100 according to one embodiment may include an acquisition unit 111, a determination unit 112, a notification unit 113, and a display unit 114 as functional units.

The acquisition unit 111 may record the location information record in the location information recording unit 131. Note that the acquisition unit 111 may acquire the location information record from the communication device 200 when the administrator requests the location information record at an arbitrary timing. For example, the acquisition unit 111 may request the communication device 200 to transmit the location information record when receiving an operation from the administrator.

The determination unit 112 determines the movement pattern of the communication device 200 based on the plurality of location information records. Specifically, for example, the determination unit 112 may determine the movement pattern based on a plurality of location information records acquired from the communication device 200.

The notification unit 113 notifies the administrator of the mobile object according to predetermined conditions. Specifically, for example, the notification unit 113 may transmit a notification depending on the determination result of the determination unit 112.

The display unit 114 is a functional unit that controls the display of information regarding management of mobile objects. The display unit 114 may generate display data to be displayed on a display screen of an external device. For example, the display unit 114 displays display data that superimposes and displays a figure, a symbol, etc. indicating a position indicated in the location information included in the location information record acquired from the communication device 200 by the acquisition unit 111 on the map data. May be generated. The display data may be, for example, image data. According to this, the manager of the mobile object can visually recognize the management status, operation status, etc. of the mobile object. Note that the external device may be any device having a display screen, such as a display, a tablet terminal, or a smartphone. Further, the display unit 114 may output display data to an external device via the input/output unit 140.

Continuing to refer to FIG. 2, the information processing device 100 will be described. The recording unit 130 of the mobile object management system 10 according to one embodiment includes a location information recording unit 131, an operation plan recording unit 132, a movement pattern recording unit 133, and an area information recording unit 134 as functional units. It's fine.

The location information recording unit 131 records the location information record acquired by the acquisition unit 111. Specifically, for example, the location information recording unit 131 may be a recording device that records a database that records the location information records acquired by the acquisition unit 111.

The operation plan recording unit 132 records an operation plan for managing the operation of a mobile object. The operation plan may be information indicating a planned movement pattern of a mobile object. Specifically, for example, the operation plan is information regarding the movement schedule of the mobile object, such as a timetable, the scheduled travel route of the mobile object, and the scheduled time to depart from or pass through one or more points set on the planned travel route. It's good. Further, the operation plan recording unit 132 may be, for example, a recording device that records a database. That is, the operation plan recording unit 132 may record a plurality of operation plans.

The movement pattern recording unit 133 records the movement pattern determined by the determination unit 112. The movement pattern recording unit 133 may be, for example, a database.

The area information recording unit 134 records information on an area defined based on a plurality of coordinate information specified in advance. Specifically, for example, the area information recording unit 134 records a plurality of pieces of coordinate information in association with each other.

The area information recording unit 134 may store information on the valid time of each area. The area information recording unit 134 may store information on each area and information on the validity period of each area in association with each other.

FIG. 5 is an example of a location information record recorded by the location information recording unit 131. The location information recording unit 131 records the location information record acquired by the acquisition unit 111.

Note that the location time included in the location information record is not limited to the above example. For example, the location time may be the time when the acquisition unit 111 acquired the location information record. That is, for example, the location information recording unit 131 may record the location information that the acquisition unit 111 acquired from the communication device 200, the identification information, and the time at which the acquisition unit 111 acquired the location information as a location information record. .

FIG. 6 is an example of an operation plan recorded by the operation plan recording unit 132. The operation plan recording unit 132 may record a plurality of operation plans. The operation plan recording unit 132 may record a list of scheduled passage times for each point in each operation plan.

An example of information recorded by the movement pattern recording section 133 will be described with reference to FIG. 7. For example, the movement pattern recording unit 133 may record the movement pattern determined by the determination unit 112, identification information that uniquely identifies the communication device 200, and time information of the movement pattern in association with each other.

<Determination of direction of travel>
The determining unit 112 may determine the traveling direction of the communication device 200 as the movement pattern. For example, the determining unit 112 may determine the traveling direction of the communication device 200 based on the order of location information records specified based on the location times included in each of the plurality of location information records acquired from the communication device 200.

An example of a method for determining the traveling direction by the determination unit 112 will be described with reference to FIG. 8 . FIG. 8 is a diagram showing an example of movement pattern determination by the determination unit 112.

In the example of FIG. 8, the communication device 200 is mounted on a mobile body V moving on a route R1. Further, in FIG. 8, an arrow A1 indicates the traveling direction of the moving body V on the route R1, and a point P1 and a point P2 on the route R1 indicate points from which the communication device 200 has acquired location information. The time indicates the location time at the points P1 and P2, respectively. Further, the point L1 is an arbitrary point on the route R1. The point L1 may be, for example, a point indicated by latitude and longitude. Specifically, for example, the point L1 is defined by the latitude and longitude specified by the administrator. Further, the point L1 may be, for example, a name indicating a specific point on the route R1. Specifically, for example, the point L1 may be the name of a stop, intersection, etc. on the route R1.

The determining unit 112 may determine the traveling direction of the communication device 200 by referring to the location information acquired at the points P1 and P2. Specifically, for example, the determination unit 112 determines the order of the location information at points P1 and P2 based on the location time, and moves the communication device from the point indicated by the earlier location information to the point indicated by the later location information. It may be determined that 200 is in progress. For example, in FIG. 8, the location time at point P1 is earlier than the location time at point P2. In this case, the determination unit 112 may determine that the communication device 200 is moving in the direction indicated by arrow A1. According to this, when there are communication devices 200 moving in different directions on the same route, it is possible to distinguish between them and manage them. That is, according to an embodiment of the present invention, it is possible to manage moving objects V managed by a plurality of operation plans on one operation management system, and it is possible to manage moving objects V to be managed in a unified manner. can. Note that if the location time at P1 is later than the location time at P2, the determination unit 112 may determine that the communication device 200 is moving in the opposite direction to the direction indicated by the arrow A1.

<Judgment of passing>
Further, the determination unit 112 may determine passage of the communication device 200 at a predetermined point as the movement pattern. For example, based on a plurality of location information records acquired from the communication device 200, the determination unit 112 determines whether the communication device 200 passes at a predetermined point on the movement route of a mobile body equipped with the communication device 200, and the communication device 200. The time when the vehicle passes a predetermined point (hereinafter also referred to as "passing time") may be determined.

Referring again to FIG. 8, an example of a method for determining passage by the determination unit 112 will be described. The determining unit 112 may determine that the vehicle has passed through the point L1 by referring to the location information acquired at each of the points P1 and P2. For example, the determination unit 112 may determine that the communication device 200 has passed through the point L1 based on the positional relationship between the points P1 and P2 and the point L1. Specifically, for example, the determination unit 112 determines the traveling direction of the communication device 200 based on the order of the location times at the points P1 and P2, and determines that the point L1 exists in the traveling direction seen from the point P1, and If the point L1 does not exist in the direction of travel seen from P2, it may be determined that the communication device 200 has passed the point L1. Moreover, either one of the location times at points P1 and P2 may be used as the passing time at point L1. For example, if the location time at point P1 is 10:00:00 and the location time at point P2 is 10:01:00, 10:00:00 or 10:01:00 is used as the passing time at point L1. It's fine. Furthermore, the central time of the location times at points P1 and P2 may be used as the passing time at point L1. For example, if the location time at point P1 is 10:00:00 and the location time at point P2 is 10:01:00, 10:00:30 may be used as the passing time at point L1. According to this, for example, the communication device 200 can reflect the time of arrival at a predetermined point on the traffic management system, and when managing mobile objects V moving on the same route at different times, You can understand the difference in time required for each band. That is, the traffic situation around the mobile body V equipped with the communication device 200 can be reflected on the management system.

<Determination of whether a moving object is located within the area>
Further, the determination unit 112 may determine, as the movement pattern, whether the communication device 200 exists inside or outside a predetermined area. For example, it may be determined whether the point indicated by the location information record acquired from the communication device 200 is located inside or outside a predetermined area.

An example of a method for determining whether the communication device 200 is located inside or outside a predetermined area by the determination unit 112 will be described with reference to FIG. 9. In FIG. 9, points P1 to P3 are positions indicated by a plurality of pieces of location information acquired by the acquisition unit 111 from one communication device 200. The area AR1 is an area that has a plurality of points whose positions are known as vertices and is divided by line segments connecting the vertices. Each vertex may be defined by coordinate information specified by latitude and longitude. The coordinate information may be recorded in the area information recording unit 134, which will be described later. For example, in FIG. 9, area AR1 is shown as a rectangular area whose vertices are coordinates C1, C2, C3, and C4 indicated by known coordinate information. Note that the area AR1 may be defined by three or more pieces of coordinate information, and there are no particular limitations on how the area AR1 is defined. Furthermore, the area AR1 may be defined by an address. Further, in the example of FIG. 9, one area AR1 is defined, but a plurality of areas AR1 may be defined in one mobile body management system 10.

In addition, in FIG. 9, two broken lines (hereinafter also referred to as horizontal lines) extending horizontally to the left toward the map plane and two horizontal lines hypothetically starting from point P1 and point P3, respectively, are shown. Two dashed dotted lines (hereinafter also referred to as vertical lines) are shown that are orthogonal and extend vertically downward toward the map plane.

The determining unit 112 may determine whether the communication device 200 is located inside or outside the area AR1 based on the number of times the horizontal line and the vertical line intersect with the sides forming the area AR1.

Here, when a horizontal line is drawn in one direction (in the example of FIG. 9, to the left when facing the map) starting from a point located inside the predetermined area, the horizontal line and the sides that make up the predetermined area are: Always intersect only an odd number of times. Also, when a horizontal line is drawn in one direction (in the example in Figure 9, to the left when facing the map) from a point located outside the predetermined area, the horizon and the sides that make up the predetermined area are once either do not intersect, or intersect an even number of times. Similarly, when a vertical line is drawn in one direction perpendicular to the horizon (in the example of FIG. 9, downward toward the map) starting from a point located inside a predetermined area, the vertical line and the predetermined area It always intersects the edges that make up only an odd number of times. Also, when a vertical line is drawn in one direction (downward toward the map in the example in Figure 9) perpendicular to the horizon starting from a point located outside the predetermined area, the vertical line and the predetermined area are formed. The edges that do intersect either never or an even number of times. From this, if the sides forming the area and the horizontal line and vertical line starting from a certain point intersect each other an odd number of times, it can be determined that the point is located inside the area. Additionally, if the sides that make up the area and at least one of the horizontal or vertical lines starting from a certain point never intersect or intersect an even number of times, the point is determined to be located outside the area. can do.

In the example of FIG. 9, the determining unit 112 may determine that the point P1 is located inside the area AR1. Specifically, in the example of FIG. 9, a horizontal line starting from point P1 intersects an odd number of sides forming area AR1, and a vertical line starting from point P1 intersects an odd number of sides forming area AR1. Since the points intersect twice, the determining unit 112 may determine that the point P1 is located inside the area AR1. Further, in the example of FIG. 9, the determining unit 112 may determine that the point P3 is located outside the area AR1. Specifically, in the example of FIG. 9, the horizontal line starting from point P3 intersects the sides forming area AR1 an even number of times, and the vertical line starting from point P3 does not intersect the sides forming area AR1. Alternatively, since the points intersect an even number of times, the determining unit 112 may determine that the point P3 is located outside the area AR1. According to this, the administrator can grasp whether the moving object is inside or outside the predetermined area. That is, according to an embodiment of the present invention, for example, when a vehicle such as a bus or a taxi is managed as a moving object and a parking lot is set as a predetermined area, the managed vehicle starts operation. It is possible to know what has been done or stolen. Note that in the above example, horizontal lines and vertical lines were used for convenience of explanation, but it is sufficient to find the number of intersections as described above, and two half-lines (or line segments) that are perpendicular to each other with a certain point as the starting point are used. Needless to say, it is possible. That is, it should be noted that the above-mentioned number of crossings is not necessarily determined for horizontal lines and vertical lines.

Note that the above method of determining whether a region is inside or outside the area using the number of intersections is one example, and is not limited to this example. For example, if you draw a straight line starting from the point indicated by the location information record and ending at any point on the side that makes up the area, and then move the end point once around the side that makes up the area, the straight line will be the same as the starting point. It may be determined whether the area is inside or outside the area based on the number of laps around the area.

<Determination that a mobile object has left the area>
Further, the determining unit 112 may determine that the communication device 200 has entered or exited a predetermined area based on a plurality of location information records. For example, the determining unit 112 determines whether the communication device 200 has entered or left the area by determining whether each of the plurality of location information records acquired from the communication device 200 is inside or outside the area. It's fine. Specifically, for example, the determining unit 112 may determine the traveling direction based on a plurality of location information records, and may also determine whether the point indicated by each location information record is inside or outside the area. If the location information record with the earliest location time among the multiple location information records is inside the area, and the location information record with the latest location time among the multiple location information records is outside the area, the determination unit 112 , it may be determined that the communication device 200 has moved from the inside of the area to the outside (exit). Additionally, if the location information record with the earliest location time among the multiple location information records is outside the area, and the location information record with the latest location time among the multiple location information records is inside the area, the determination unit 112 may determine that the communication device 200 has moved from outside the area to inside (entered). According to this, it becomes possible to determine whether a mobile object equipped with the communication device 200 has entered or left a certain area, such as the time when the mobile object was moved from a storage location, the time when it was returned to a storage location, etc. can be managed by the administrator on the system. That is, according to one embodiment of the present invention, a manager of a mobile object can grasp whether or not the mobile object is engaged in the operation determined by the operation plan.

In the example of FIG. 9, the determination unit 112 determines that if the location time at point P1 is the earliest and the location time at point P3 is the latest, the communication device 200 has moved from the inside to the outside of the area AR1, that is, It may be determined that the communication device 200 has left the area AR1.

<Area determination according to location time>
A zone may have a predefined validity time. For example, the valid time may be defined by the start date and time and end date and time of a period during which the area is used to determine movement patterns. Specifically, for example, if a certain area is used for determining movement patterns in the period from 09:00:00 on October 1, 2021 to 18:00:00 on October 31, 2021, this period may be specified as the valid time for the area. Note that the valid time may be arbitrarily defined by the administrator, and the definition of the valid time is not limited to the above example. The valid time may be defined, for example, by the elapsed time from a specific date and time. Further, the effective time may be defined, for example, by the time during which the area is not used for determining movement patterns. Information on the valid time may be recorded in the area information recording unit 134, which will be described later.

If the location information indicates that the location is inside the area, the determination unit 112 may further determine whether the location time is included in the valid time range of the area. Specifically, for example, if there is an area whose valid time is defined as from 09:00:00 on October 1, 2021 to 18:00:00 on October 31, 2021, a point inside the area If the location time of the location information record detected in is 08:59:00 on October 1, 2021, the determining unit 112 may determine that the location information is outside the area.

With reference to FIG. 10, an example of determining whether an area is inside or outside the area based on the valid time of the area will be described. FIG. 10 is a flowchart of determining inside and outside the area based on the valid time according to one embodiment.

The determination unit 112 acquires area information from the area information recording unit 134, which will be described later (step S1). Further, the determination unit 112 obtains a location information record from the communication device 200 or the location information recording unit 131 (step S2).

The determining unit 112 determines whether the location information record is inside the area indicated by the area information (step S3). If the determination unit 112 determines that the location information record is not inside the area (No in step S3), the process moves to step S7.

If the determination unit 112 determines that the location information record is inside the area (Yes in step S3), it acquires the valid time of the area from the area information recording unit 134 (step S4).

The determination unit 112 determines whether the detection time is within the valid time of the area (step S5). When the determination unit 112 determines that the detection time is within the valid time of the area (Yes in step S5), the determination unit 112 determines that the location information is inside the area (step S6). If the determination unit 112 determines that the detection time is not within the valid time of the area (No in step S5), the determination unit 112 determines that the location information is outside the area (step S7).

According to this, for example, a manager of a mobile object can manage the mobile objects that enter and leave the managed area during business hours.

Note that the movement pattern may be any information regarding the movement or position of the communication device 200 that can be determined based on the location information of the communication device 200, and is not limited to the above example. For example, the movement pattern may be a movement speed at which the communication device 200 moves, a movement route that the communication device 200 moves, or the like.

Furthermore, the information processing device according to another embodiment may be capable of managing the operation of a moving body that moves in the height direction. The information processing device 100 according to another embodiment may determine a movement pattern based on position information including altitude information, for example. For example, the vertical movement pattern may be determined based on altitude information, and it may be determined that a predetermined altitude has been passed. Alternatively, the area may be defined as a space by adding altitude in addition to latitude and longitude to the coordinate information that defines the area. According to this, the information processing apparatus 100 according to another embodiment can also manage the operation of flying objects such as drones, UAVs (unmanned aerial vehicles), and aircraft.

Here, if a plurality of moving bodies operate according to different operation plans, a plurality of operation plans will exist on the mobile object management system 10. In this case, in order to manage each communication device 200 and the operation plan in association with each other, a means for grasping which operation plan is assigned to which communication device 200 is required. That is, a means for grasping the relationship between the communication device 200 and the operation plan is required.

In contrast, the mobile object management system 10 according to one embodiment is capable of determining the relationship between the pre-stored operation plans of a plurality of mobile objects and the determined movement pattern of the communication device 200. can. Note that in the mobile object management system 10 according to one embodiment, the information processing device 100 may store the operation plan in the operation plan recording unit 132 in advance.

With reference to FIG. 11, an example of a method for determining the relationship with the operation plan based on the movement pattern of the communication device 200 will be described. In FIG. 11, a broken line arrow from point P1 to point P6 indicates a route R1 along which the communication device 200 is scheduled to travel, which is determined by the operation plan A. Further, point P1, point P2, point P3, point P4, point P5, and point P6 each indicate a position where one communication device 200 has acquired location information.

The determining unit 112 determines the operation plan assigned to the communication device 200 by comparing the passing order of points on the route R1 and the order of points passed by the communication device 200 determined based on the location information record. may be determined. For example, if the order of the location information records determined from the location time is the order of point P1, point P2, point P3, point P4, point P5, and point P6, the determination unit 112 determines that the communication device 200 It can be determined that the vehicle is operating above the ground. That is, in this case, the determination unit 112 may determine that the communication device 200 is operating based on the operation plan A. Note that the relationship between the communication device 200 and the operation plan may be determined based on the minimum location information record necessary to uniquely determine the relationship between the communication device 200 and the operation plan, and the above example is sufficient. but not limited to. For example, if each operation plan has a unique passing point, it is determined that the particular passing point has been passed using the method explained using FIG. 8, and the communication device The relationship between 200 and the operation plan may be determined. Specifically, for example, among the planned travel routes, route R1 based on operation plan A passes through point L1 as a unique passing point, and route R2 based on operation plan B passes through point L1 as a unique passing point. When passing through point L2, the determining unit 112 determines that the communication device 200 is assigned to operation route A when determining that the communication device 200 has passed through point L1 based on the location information record acquired by the acquiring unit 111. You may do so.

Further, the determination unit 112 may determine the relationship between the communication device 200 and the operation plan based on the determined movement pattern and the operation plan. For example, the determination unit 112 determines based on the passing time when the communication device 200 passes a predetermined point and the scheduled time when the communication device 200 passes the predetermined point (hereinafter also referred to as “scheduled passing time”). From among the plurality of operation plans, the operation plan corresponding to the communication device 200 that has passed through the predetermined point may be determined. According to this, the relationship between moving objects and operation plans can be automatically determined based on the movement status of the moving object and reflected in the management system, so multiple operation plans that follow the same planned travel route can be automatically determined. In some cases, the relationship between the communication device 200 and the schedule can be determined.

Below, with reference to FIG. 12, an example of a method for determining the relationship between the communication device 200 and the operation plan based on the passing time will be described. In the example of FIG. 12, there are two operation plans, operation plan A and operation plan B, that follow route R1. Furthermore, there are three points on the route R1: a point P0 (starting point), a point P1 (intermediate point), and a point P2 (end point). The points P0 to P2 are located on the route R1 and are points, such as stops or stations, for which the passage time of the communication device 200 is determined in the operation plan.

In the example of FIG. 12, in operation plan A, the scheduled passing time of the communication device 200 at point P1 is determined as 10:05:00 (hereinafter referred to as "10:05:00"), and in operation plan B Assume that the scheduled passage time of the communication device 200 at the point P1 is determined to be 10:35:00. Assume that the passing time of a certain communication device 200 at point P1 is 10:05:00, as determined by the determination unit 112 based on the location information record. In this case, since the passing time matches the scheduled passing time of the operation plan A, the determination unit 112 may determine that the communication device 200 is operating based on the operation plan A. That is, the determination unit 112 may determine the operation plan A as the operation plan of the communication device 200.

On the other hand, the passing time and the scheduled passing time do not necessarily match. For example, a mobile object may depart from a stop or station earlier than the predetermined time (early departure) or later than the predetermined time (late departure) due to the influence of traffic conditions such as traffic volume and road construction. Sometimes. For example, when the scheduled passing time of point P1 is 10:05:00 (scheduled passing time A) in operation plan A and 10:35:00 (scheduled passing time B) in operation plan B, the judgment is made. If the passing time of the communication device 200 at the point P1 determined by the unit 112 is 10:30:00, there is a possibility that a delay of 25 minutes (1500 seconds) has occurred for operation plan A, and a 5 minute delay for operation plan B. There are two possible ways in which the premature onset (300 seconds) may have occurred. In this regard, in Japan, there is a ministerial ordinance (for example, Railway Ministerial Ordinance No. 3 of 1942) that prohibits early departures for moving vehicles such as buses and trains that operate based on operation plans. We are taking various measures to prevent this from occurring. Therefore, moving objects often start late rather than early. That is, in the above example, it is more likely that the operation plan A, which is a late departure, is the operation plan of the communication device 200 than the operation plan B, which is an early departure. In other words, when determining the operation plan, it is necessary to consider the possibility of a late departure. Additionally, although bus companies take measures to prevent early departures as mentioned above, there are times when they are forced to depart early, for example, if the next bus arrives earlier than scheduled. obtain. In other words, when determining the operation plan, it is also necessary to consider the possibility of early departure. Therefore, when determining the operation plan, it may be necessary to consider the possibility of early or late departures depending on traffic conditions.

In one embodiment, the determination unit 112 determines the relationship between the communication device 200 and the operation plan based on the distance in seconds obtained by assigning a predetermined weight to the difference between the passing time and the scheduled passing time at the point P1. may be determined.

The distance in seconds may be determined by the following formula.

In the above formula, the difference between the passing time and the scheduled passing time may be calculated as the number of seconds. For example, if the passing time is 10:00:00 and the scheduled passing time is 10:01:00, the difference may be determined as 60 seconds. Note that the difference between the passing time and the scheduled passing time may be determined in any unit, and may be determined in minutes or hours.

In the above formula, k indicates the order on the route of points at which passing times are measured. Further, n is the maximum number that k can take, that is, the order of the last point on the route, that is, the end point.

In the above equation, ω is a constant term indicating a weight determined for each point that the moving object passes. Specifically, ω is a constant term that is set for each point that a moving object passes, and indicates the tolerance for late departures in the operation plan that may occur until the moving object reaches a predetermined point. It may be. Here, at the starting point of the route, traffic conditions are less likely to affect the operation, so it is less likely that the starting point will depart late from the operation plan. On the other hand, as the train approaches the end point, traffic conditions along the route tend to affect the operation, so late departures are more likely to occur at points closer to the end point. Therefore, ω may be set to a larger value as the distance traveled from the starting point is shorter, and ω may be set to a smaller value as the distance traveled from the starting point is longer. For example, ω may be the number of points existing on the route after each point. Further, for example, ω may be the reciprocal of the number of points passed. According to this, the possibility that a late departure will occur at each point from the starting point to the ending point is taken into consideration when determining the operation plan. That is, according to one embodiment of the present invention, it is possible to determine a travel plan in consideration of late departures due to traffic conditions.

In the above formula, p is a variable term indicating a weight determined for each point that the moving object passes through. Specifically, p is a variable term that changes depending on the difference between the passing time of the moving object and the expected passing time at a predetermined point, and is a variable term that changes depending on the difference between the passing time of the moving object and the scheduled passing time, and is This is a variable term that indicates the degree of tolerance for premature onset.

As mentioned above, it is necessary to consider the possibility of early departure when determining the operation plan. Therefore, in the above formula, if the value obtained by subtracting the estimated passing time from the passing time is less than 0 (in the case of an early departure), if the value obtained by subtracting the estimated passing time from the passing time is 0 or more (in the case of an early departure) It is desirable that the value of the distance in seconds is larger than the case where the distance is not set. Therefore, if the condition is not premature, p may be set to 0 in the above formula, and if the condition is premature, p may be set to a value larger than 0 in the above formula. According to this, the possibility of early departure occurring at each point from the starting point to the ending point is taken into consideration when determining the operation plan. That is, according to one embodiment of the present invention, it is possible to determine the operation plan in consideration of early departure due to traffic conditions.

Furthermore, with reference to FIG. 12, determination of the relationship between the communication device 200 and the operation plan using distance seconds will be described. First, the determination unit 112 of the information processing device 100 according to an embodiment uses the above-mentioned formula to determine the distance seconds (distance seconds A) and the distance seconds (distance seconds A) between the passing time and the scheduled passing time of the operation plan B. B) may be calculated. Here, since point P1 is the second point in operation plan A and operation plan B, ω is temporarily assumed to be 2. Further, for operation plan A, p is set to 0 because the train leaves late, and for operation plan B, p is temporarily set to 100 because it leaves early. Therefore, in this example, distance seconds A is "3000" and distance seconds B is "30600". In this case, when distance seconds A and distance seconds B are compared, distance seconds A is smaller, so the determination unit 112 can identify the operation plan A as the operation plan corresponding to the communication device 200A. In this way, according to one embodiment of the present invention, an appropriate operation plan can be determined in consideration of traffic conditions. Note that in the above example, the values of ω and p are merely examples, and the values are not limited to these.

The determination unit 112 may record the identification information of the communication device 200 and the operation plan in the operation plan recording unit 132, which will be described later, based on the result of determining the relationship between the communication device 200 and the operation plan.

Furthermore, the determination unit 112 may determine that the communication device 200 has finished the assigned service based on a predetermined condition. The predetermined condition may be, for example, that the communication device 200 has passed a point defined by latitude and longitude. Specifically, for example, if the determination unit 112 determines that the communication device 200 has passed a predetermined point on the travel route determined by the travel plan using the method described using FIG. , it may be determined that the operation based on the operation plan has ended. Further, the predetermined condition may be time information. Specifically, for example, the determination unit 112 determines that the communication device 200 has finished the operation based on the allocated operation plan when the current time has passed the operation end time determined by the operation plan. good. Note that the predetermined conditions may be recorded in advance in the operation plan recording unit 132, which will be described later, in a form that is included in the operation plan. According to this, for example, the operation status indicating whether each communication device 200 is operating based on the operation plan can be managed.

Here, for an administrator who manages a large number of moving objects, it may be difficult to grasp the status of all moving objects and perform appropriate management according to the situation. For example, if the communication device 200 breaks down, it becomes impossible to manage the operation of the mobile body to which it is attached, causing problems in management. Conventionally, in order to prevent such inconveniences, an administrator regularly inspects the communication device 200. However, for example, for an administrator who manages a large number of mobile objects using a large number of communication devices 200, it may be inefficient to inspect all communication devices 200. Therefore, when there is a communication device 200 in a predetermined situation among the large number of communication devices 200, a means for notifying the administrator is required.

The notification unit 113 of the information processing device 100 according to an embodiment may notify the administrator when the movement pattern determined by the determination unit 112 matches a predetermined condition set in advance. For example, if the mobile object does not pass a predetermined point defined in the operation plan, the notification unit 113 may determine that the communication device 200 has failed to transmit the location information record, and may indicate that the communication device 200 has failed. You may notify the administrator. Specifically, for example, the notification unit 113 may issue a notification if the determination unit 112 does not determine that the communication device 200 has passed through the predetermined point within a predetermined time from the scheduled passage time at the predetermined point. You can go. According to this, for example, if a situation occurs in which location information cannot be transmitted normally to the information processing device 100 due to a failure of the communication device 200, the administrator recognizes the abnormality and repairs the communication device 200. We can perform maintenance such as replacement.

In another embodiment, the notification unit 113 notifies the administrator of the mobile body when the determination unit 112 determines that there is a communication device 200 that has entered or exited a predetermined area. You can go. For example, the predetermined area may be a waiting area for a mobile object. Specifically, when the determination unit 112 determines that the communication device 200 has entered a waiting area that is preset as a predetermined area using the method described using FIG. You may give notice. By doing so, the administrator can grasp whether or not a mobile object is present in the waiting area, and can easily manage the mobile object. Note that the conditions under which the above-mentioned notification unit 113 sends the notification to the administrator are merely examples, and any conditions may be set as long as they are based on the movement pattern determined by the determination unit 112.

The display unit 114 generates display data for distinguishing between the location information record acquired from one communication device 200 and the location information record acquired from another communication device 200 and displaying the information superimposed on the map data. good. Specifically, for example, a common method such as a different color, shape, or pattern is assigned to each communication device 200 based on the identification information included in the location information record, and location information obtained from each communication device 200 using the common method is assigned. Display data for distinguishing and displaying records may be generated. That is, by plotting the points indicated by the location information records acquired from one communication device 200 on map data using a common method, the communication device 200 from which the location information record is acquired is distinguished from other communication devices 200. May generate display data.

The display unit 114 may generate display data in which a figure indicating a predetermined area is superimposed on the map data together with the location information record. According to this, the manager of the mobile object can visually confirm information on the area used for managing the mobile object.

The display unit 114 may generate display data for distinguishing and displaying areas within the valid time and areas not within the valid time, based on information on the valid time of the area. Specifically, for example, the display unit 114 compares the current time with information on the travel time of the area, and displays a graphic indicating an area where the current time is within the valid time and a figure indicating the area where the current time is not within the valid time. Graphics indicating areas may be distinguished by different aspects (for example, color, pattern, shape, etc.), and display data to be displayed superimposed on map data may be generated. That is, the display unit 114 may change the shape of each area into a different form based on the valid time of the area and the current time. According to this, the manager of the mobile object can visually confirm for each area whether or not the area is within the valid time period.

An example of display data generation processing by the display unit 114 will be described with reference to FIG. 13. FIG. 13 is an example of display data displayed on the display screen of the external device. In FIG. 13, point P1, point P2, and point P3 are points based on the location information record acquired from the communication device 200A. Further, point P1' is a point based on the location information record acquired from communication device 200B. Areas AR1 and AR1' are areas with different valid times. Area AR1 is an area where the current time is within the valid time. Furthermore, the area AR1' is an area where the current time is not within the valid time of the area AR1'.

The display unit 114 may generate display data for displaying each location information record in a different manner based on the identification information included in the location information record. For example, display data may be generated to display location information records obtained from a certain communication device 200 in blue and location information records obtained from another communication device 200 in red, superimposed on map data. . By doing this, the manager of the mobile object can understand that, for example, point P1, point P2, and point P3 are the location information records acquired from the communication device 200A, and point P1' is the location information record acquired from the communication device 200B. Even when location information records obtained from multiple communication devices 200 are mixed and displayed on map data, each mobile object can be easily managed. can.

The display unit 114 may distinguish each area in a different manner, for example, using a different color or a different pattern, based on the valid time of the areas AR1 and AR1'. For example, display data for displaying areas within the valid time in blue and areas outside the valid time in red may be generated to be superimposed on the map data. By doing this, the manager of the mobile object can visually recognize, for example, that area AR1 is within the valid time and area AR1' is not within the valid time. Even when a plurality of areas are displayed together on the map data, the status of each area can be easily confirmed.

The display unit 114 can acquire a plurality of pieces of coordinate information for defining area information and record it in the area information recording unit 134. For example, the display unit 114 can acquire coordinate information of each vertex of an arbitrary figure drawn by the administrator on an image based on map data, and record it in the area information recording unit 134. . According to this, since the administrator can define the area to be managed while referring to the map data, usability can be improved.

It will be apparent to those skilled in the art that various changes or improvements can be made to the embodiments described above.
